What does Maytag Dishwasher E3 Error - Causes & Fix mean?

E3 on a Maytag dishwasher signals a control system fault. Most clear after a one-minute power reset, otherwise check the control board or wiring.

How do I fix Maytag Dishwasher E3 Error - Causes & Fix?

Follow the step-by-step diagnosis below. The most likely fix is identified by checking power, sensor resistance, and control-board signals in order — using a multimeter and the part numbers documented in the parts reference table.

Can I keep running the equipment with E3 active?

Generally no. Faults on Appliance units are emitted when a sensor, safety, or control circuit is outside its operating envelope. Running through an active fault risks compressor, heater, or control-board damage. Diagnose and clear the fault first.

What part is most commonly replaced for Maytag Dishwasher E3 Error - Causes & Fix?

The most frequently replaced parts for Maytag Dishwasher E3 Error - Causes & Fix are listed in the Parts Reference section of this guide with OEM part numbers and typical price ranges. Check the table for direct replacements.

Is Maytag Dishwasher E3 Error - Causes & Fix a DIY repair or do I need a technician?

Sensor swaps, fan motor replacements, and condenser cleaning are typical DIY-level repairs. Anything involving refrigerant, gas, or high-voltage (>240V) work requires a licensed technician for both safety and code-compliance reasons.

Maytag Dishwasher E3 Error — What It Means

The E3 error on a Maytag dishwasher indicates a control-related fault. According to Maytag’s product help, this code points to an issue within the dishwasher’s control system rather than a mechanical wash problem. The manufacturer recommends a power-cycle reset as the first step. If the code clears and stays off, it was likely a temporary software glitch. If E3 returns after the reset, the problem lies in the control board, user interface, or associated wiring and will require inspection or replacement of those components.

Jump to Fix

Common Causes

Transient control glitch or software lockup A temporary fault in the control logic that clears after a full power reset.
Defective main control board The appliance control unit has failed and continues to throw E3 after reset.
Failed user interface or control panel The UI assembly has an internal fault and cannot communicate properly with the main board.
Loose, damaged, or corroded wiring connections Connectors between the control board and user interface are compromised, causing intermittent or permanent communication loss.

Step-by-Step Fix

Verify the model number from the door jamb or tag and consult the service manual or tech sheet for the exact E3 definition, as Maytag’s consumer pages are generic.
Perform a power reset by unplugging the dishwasher or turning off the circuit breaker for one full minute, then restore power.
Run a test cycle after the reset to see if the code clears and the dishwasher operates normally.
Inspect all control-side wiring if E3 returns, looking for loose harness plugs, damaged pins, corrosion, or heat damage at the main control board and user interface connectors.
Replace the main control board or user interface depending on which component your model-specific diagnostics identify as faulty, ensuring all connectors are clean and seated.
Restore power and run a verification cycle to confirm the E3 code does not reappear and that all wash functions work correctly.
Document the repair by noting the part number replaced and any wiring repairs made for future reference.

Parts Often Needed

Part	Notes
Main control board / appliance control unit	Amazon \| Replace if E3 persists after reset and wiring checks pass.
User interface / control panel assembly	Amazon \| Some models integrate the UI into the console, verify your model’s parts breakdown before ordering.
Wiring harness or connector kit	Amazon \| Order if connectors are heat-damaged, corroded, or have broken pins.

When to Call a Pro

If the E3 code returns after a power reset and you are uncomfortable working with live electrical components or removing the dishwasher console, call a qualified appliance technician. Control board and user interface replacement require safe handling of 120 V wiring and proper diagnosis to avoid replacing the wrong part. A professional can also cross-reference the model-specific service manual to pinpoint whether the fault is in the board, UI, or a related harness, saving time and the cost of unnecessary parts.
